Stackwise virtual on Cisco 3850, switch get removed automatically from stack

[mumbai.support]

Hi All,

We have pair of Cisco 3850-48S and we have configured stackwise virtual on switches. for sometime this is working fine and both switches shows in stack.

But after some days either switch gets automatically gets removed from stack and after hard boot switch join the stack.

Anyone faced this kind of issue?

thanks

Hello

I assume you have the same make/model/license/software for each physical switch?
Its also possible your having intermittent issues with you VSL connections, do you have VSL and DAD redundancy configured (multiple links)?

What messages or logging is being reported?

What firmware is the virtual stack running on?
